The crowded race to become Chicago’s mayor is about to get a teensy bit smaller.

Amara Enyia, the West Side activist who was one of the first to challenge Mayor Rahm Emanuel, is expected to drop out of the race and endorse Ald. Bob Fioretti at a City Hall press conference this morning.

That leaves nine candidates still in the running for Emanuel’s job.

“My vision for Chicago ... has resonated with everyday people who are looking for a different kind of leadership,” Enyia said in a statement. “However, it has become clear that Alderman Fioretti is better positioned to carry this message forward. Therefore, I am withdrawing from the race and am endorsing Bob for Mayor of Chicago and will work vigorously on his behalf.”
